In an effort to identify an idealized information technology (IT) system for education and training that could be implemented within a 10- to 15-year period, this paper looks at likely hardware configurations in the home, workplace, and educational institutions; identifies teachers' needs for IT systems that are not currently being met at a price suitable for education and training purposes; and specifies training functions that an idealized system might meet. Those functions that might be best left to teachers are examined, as well as those that might best be accommodated within an IT system. The paper concludes by suggesting two rather different types of idealized systems. In the first, a hierarchical model, teaching materials are centrally designed and produced, and all teaching functions are accommodated within the system. In the second, a networking model, IT is used primarily for facilitating communications between teachers and learners, and the teachers and learners create their own materials. It is noted that, in the end, what might appear to be a technical decision about requirements will ultimately depend on political priorities. (Author/DJR)
